looks like it is the Aussie version of 'easy start' as it is called over here ('start ya bastard' sounds so much better though ). It will start most engines very easily and fast . But it doesn't cure flat batteries . If you do have that problem and you can get your battery out of the vehicle easily , just take it out and keep it in a frost free area over night . Then pop it back in when you want to use the vehicle. Even better while it is out , stick it on a trickle charge , problem solved .
cheers
